HP's already outed a bunchof business laptops today, but so far they've all been aimed at the enterprise level -- machines an IT manager would deploy on the order of thousands. But while it was at it, the company also refreshed its ProBook lineup for small businesses, the sort of operations that likely don't have an IT department running the show. For those folks, there's the refreshed b- and s-series. Starting with the "b" lineup, it includes 14- and 15.6-inch models (the 6470b and 6570b), each of which have a magnesium-reinforced chassis with a coating designed to resist scratches and other signs of wear. Users can choose between integrated and discrete graphics, while the 14-inch version, at least, will be offered with Intel and AMD chips. (The 15-incher is Intel-only.) Other perks include Intel's vPro management technology, HP 3D DriveGuard and optional 3G / 4G connectivity. The Intel-based models will start at $769, while the AMD-based 6475b will go for $669 and up. Expect these to land on June 4th. Meanwhile, the s-series (pictured) is available in a wider range of sizes (13, 14, 15 and 17 inches), with a mix of Intel and AMD chips. The existing s-series has also gotten a redesign, with aluminum casing and a spill-resistant keyboard. These laptops, too, will arrive June 4th, though they're slated to start at a lower price of $589.Gallery-154806Gallery-154804
